“ In historical times it first attained importance on the foundation of Heraclea by the Spartans in 426 B.C. The Thessalians, jealous of the establishment of a Spartan outpost on their borders, attacked Heraclea, and in 420 the Heracleots were defeated by them with heavy loss. In the winter of 409-8 Heraclea sustained another disastrous defeat. In 395 the Thebans expelled the Spartans, and restored the city to the old Trachinian and Œtæan inhabitants. In later times Heraclea was one of the mainstays of the Ætolian power in northern Greece. ”
